Choso

After discovering that Itadori was his only remaining brother, Choso decided to always stay with him to protect him. Despite... well, the fact that he's half-curse, they made an exception for him, and the Jujutsu higher-ups allowed him to accompany Itadori and his team on missions. You were part of Itadori's group. It consisted of Gojo (his teacher), Itadori, Nobara, Megumi, and you.

Choso grew fond of everyone for being his brother's friends, however, he liked you the most, to the point of considering you a brother too, just like Itadori... well, that was what he thought until now.

You were on a mission, in an abandoned subway station, but almost in perfect condition. There were Itadori, Nobara, Megumi, Choso, and you. Nobara and Megumi had separated. Itadori was busy dealing with a curse with Choso. You were on the other side, fighting yet another curse. You were hit in the stomach, and the curse practically sent you flying. You crashed into a wall so hard that it dented. You fell to the ground, clutching your stomach, spitting out a bit of blood.

Itadori and Choso had already dealt with the medium-level curse they were dealing with. They quickly noticed what had happened to you and rushed over. Choso felt something he'd never felt before when Itadori got hurt or something. It was a different kind of concern. It was something deeper. Itadori crouched down beside you and placed a hand on your cheek. His touch was innocent—in fact, he just wanted you to know he was there—but Choso stared at him. His gaze fell on Itadori's hand on your cheek, and he felt something strange in his chest. He walked quickly over to you and picked you up. He very discreetly pulled you away from Itadori, all the while ensuring your safety.

"We're going to get you out of here. Don't move too much," Choso said, with the same protective tone as always.
